Beit known that I, RICHARD REYNOLDS,

` Jr., of the town and district of Beaufort, and

State of South Carolina, have invented a new and useful Improvement in Roller Cotton- Gins; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, in which- 1 n Figure 1 is an isometrical View; Fig. 2, a cross-section. j

The nature of my invention consistsin the arrangement of three rollers for the morcperfcc-t cleaning of long-staple cotton. l

The following is a description of the machine: In a frame consisting of two upright pieces, a, and connected at the bottom by a plank, to which they are secured, are combined three rollers. One of these rollers, b, is permanently sustained in ,the frame. This in a full-sized machine should be about seven- Just below this another roller, o, is situated, having its bearing in boxes c', that slide up and down in the frame. This is kept pressed upagainst that above it by springs d, that the boxes rest on, and which are made adjustable at pleasure. There is a square mortise made through the uprights at right angles to the rollers, and horizontal, through which square rods c pass,

- O11 one end of which a bearing, e', is made to reother ends of each ofthe rods there is a spring,

g, which draws theroller f toward the two small Ones.

ton is fed in between them, the springsyield- .ing if there is a large quantity fed iniat a time. Thecotton is then carried up between the upper roller and the large one behind it. The rollers b c are so small that they present a very obtuseangled space between them, j which prevents the cottonseed from being` crushed and drawn in while the cotton is drawn out between the upper roller and the l large one behind without injuring the staple, and with much greater rapidity, and straightcr than those now in common use.

Ido not claim as my invention the employc The manner in which I have arranged the three rollers b, o, and f, so that the cotton shall enterbetween the small rollers Z) and c, and then pass between the roller b and large roller f, by having them so arranged that the l rollers c and f are pressed by the springs against the roller b, as herein described.

The strength of this spring can` be tempered by a screw `on the end of the rod. `The two small rollers are `fluted and the cot-
